• Abstract This study presents Fiber Reinforced
  Plastic (FRP) composite components used in
  temporary bridge for emergency relief. There are
  some advantages of FRP, including light weight,
  high strength, weather resistance and easy
  storage, making FRP suitable for temporary
  bridge. There are two types of FRP temporary
  bridge in this study. First type is pedestrian
  bridge. Second type is vehicular bridge. The
  pedestrian bridge is suspension bridge made by
  the cable, FRP deck, FRP bar and FRP frame. Use
  SAP2000 to establish the numerical model. Load
  several different types of loads to simulate the
  real load and check the safety factor. Finally,
  make the FRP suspension bridge. The vehicular
  bridge use FRP beam-deck system as
  superstructure. Use SAP2000 to establish the
  numerical model. Establish the numerical model of
  different spans. The type of the load is
  according to the design of bridge code. Then
  check the safety factor. Finally, make the best
  type of FRP vehicular bridge.
